We would like to introduce our "Vibration Control Measures for Presses and Hammers." Presses and forging hammers used in metal forming generate significant kinetic energy, a portion of which is dissipated into the ground, resulting in high vibration levels. In presses, vibrations are primarily generated by the instantaneous release of stress occurring in the press frame during the metal forming process. By utilizing our viscous damper "VISCODAMPER integrated coil spring vibration isolation device" for direct support, it is possible to reduce the foundation, thereby lowering costs and construction time. 【Features】 - Reduction of heavy foundation blocks allows for decreased construction time and costs. - Vibration-sensitive equipment can be installed adjacent, improving production efficiency. - Compared to conventional methods, the reduction in vibration is achieved by at least 80% for hammers and 90% for presses. - The viscous damper contributes to improved stability of the machinery and vibration isolation effects. - Level adjustments for presses and hammers due to foundation settlement or tilting are made easy. *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts installation and adjustment work for viscous dampers and spring elements, as well as installation supervision work and measurement and analysis of vibrations and solid sounds generated by machinery and equipment. We provide economical vibration isolation foundations that meet customer requirements for various types of equipment. The technology for reducing vibrations has been researched and refined at Gelb for many years to ensure the safety and reliability of machinery. If you are troubled by even very small vibrations or noise in your surroundings, Gelb is here to support you. 【Areas of Activity (Partial)】 ■ Installation and adjustment work for viscous dampers and spring elements, as well as installation supervision work ■ Measurement and analysis of vibrations and solid sounds generated by machinery and equipment ■ Engineering from the provision of fabrication drawings for both reinforced structures and reinforced concrete structures to construction supervision ■ Foundation design for machinery and equipment or building structures, considering cost-effectiveness based on customer specifications *For more details, please download the PDF or feel free to contact us.

The "GERB Vibration Isolation" is a vibration isolation system that uses an isolation frame to provide resistance against locking motion during clutch/brake operations. This device employs very high damping force to quickly stabilize the amplitude of the press, achieving comfortable and efficient workability. Additionally, it has numerous delivery records within the country. 【Features】 ■ Responds to locking motion (back-and-forth shaking) ■ Vibration isolation system using an isolation frame ■ Utilizes very high damping force ■ Quickly stabilizes the amplitude of the press *For more details, please download the PDF or feel free to contact us.

The "vibration isolation device" using polyurethane vibration-damping material developed by our company for vibration countermeasures in press machines is excellent in weather resistance and oil resistance. Additionally, compared to rubber vibration-damping materials, it does not suffer from aging degradation and can be used for long periods. Despite its compact size, it achieves a vibration reduction effect of 10 to 20 dB, efficiently reducing vibrations and contributing to the improvement of the on-site environment. It can be easily installed on small and medium-sized press machines, and height adjustments can be made using height adjustment bolts. 【Features】 ■ Supports various loads ■ Excellent vibration isolation effect ■ Long-term usability *For more details, please download the PDF or feel free to contact us.
